The ''field'' filter operator filters the current list to leave only the first tiddler that has a distinct value for a specified date field.
|
|
|
|
For example:
|
|
|
|
|!Filter String |!Description |
|
|
|`[eachday[created]]` |Returns a list of the first tiddler created on each distinct day |
|
|
|
|
The ''eachday'' operator can be used to group tiddlers. For example, the following wiki text creates a list of the number of tiddlers that were modified on each day:
|
|
|
|
<$list filter="[!is[system]eachday[modified]!sort[modified]]">
|
|
|
|
<$view field="modified" format="date" template="DD MMM YYYY"/>: <$count filter="[sameday{!!modified}]"/> modifications
|
|
|
|
</$list>
